DISINFECTING MEANS OR ATTACHMENT FOR THE FLUSHING- ARRANGEMENTS 0F WATER-CLOSETS, URINALS, SINKS, AND THE LIKE.

Application filed June 28, 1919.

To all whom it may concern Be it known that we, JOSHUA AARON LEWIN, a subject of the King of Great Britain, and GEORGE PILCHER BARTLETT, a subject of the King of Great Britain, both residents of Durban, i atal Province, Union of South Africa, have invented certain new and useful Improvements in Disinfecting Means or Attachments for the Flushing Arrangements of Tater-Closets, Urinals, Sinks, and the like, of which the following is a specification.

This invention relates to disinfecting means or attachments for the flushing arrangements of water closets, urinals, sinks and other conveniences, receptacles, appliances or contrivances which are cleaned or flushed out by a usually regulated supply of water. A

Such flushing arrangements are commonly operated by means of a pull which, through the medium of a lever, operates the means controlling the discharge or the water from the cistern or tank to the closet, urinal,

sink, etcetera.

The object of the present invention is to provide a disinfecting means or attachn'ient which will be actuated by the said flushing stream in its passage from the cistern to the closet pan, etcetera. The disinfecting arrangement is such that upon the operation or movement of the pull or its equivalent a suitable quantity of the disinfectant is mixed with a suitable quantity of the flushing water and the mixture then flows down the flushing or wash down pipe to the point of discharge in the closet, etcetera. The arrangement is so designed that a quantity of the disinfecting mixture passes through the pipe to the closet after the main flushing'stream has passed therethrough.

The apparatus or arrangement in its preferable form includes a pivoted member which on the one side enters the flushing or wash down pipe and on the other side enters a chamber or compartment in which the disinfectant is mixed with the water. The one end of this member is shaped so that when it is depressed by the flushing water flowing down the pipe it diverts a quantity of said main flushing stream into the mixing chamber. The other end of the device operates a valve or valve device 'which admits a quantity of the disinfectant to such chamber or compartment to mix I Specification of Letters Patent.

with the water. A small passage or conduit leads from the bottom of the mixing chamber to the wash down pipe through which the mixture flows. This construction insures that all the disinfecting mixture does not leave the mixing chamber until after the main flushing stream has passed down the plpe, so that a quantity is delivered after the passage of said mainflushing stream and serves for disinfecting the water which remains in the closet pan, etcetera, until the flushing arrangement is again operated.

The invention will be more fully described with the aid of the accompanying drawings Wherein- Figure l is a perspective view partly in section of the disinfecting means or attachment applied to the flushing arrangement of a water closet, and showing the parts in the operative position.

Fig. 2 is a similar'view also partly in section of certainparts of the arrangement in the other andinoperative position.

In the drawing A represents the cistern of an ordinary flushing arrangement for a water closet. B the Wash down or flushing pipe down which the main v flushing stream flows from the cistern A to the pan C of the closet. a is the pull for operating the means which control the discharge of the water from the cistern A in any ordinary or convenient manner. The disinfecting means or attachment comprises a vessel or con tainer A which is made of the requisite size or capacity and may be made of metal or any other suitable material. In the particular construction illustrated the vessel A is divided into two chambers or compartments a a by the plate a which may be secured in position in any suitable manner. The upper chamber or compartment a is utilized as the holder or container for the disinfecting material and the lower chamber or compartment a is used as the chamber or compartment in which the disinfecting mate-; rial is mixed with the water and from which the mixture is delivered to the wash down pipe B, as hereinafter explained.

The vessel A may be constructed in one piece with or be suitably attached. to a bracket or part at which serves for fixing it, by means of bolts after other suitable means, to a further bracket or part a which is secured to the pipe B in a convenient position. The parts a and a may be constructed in one piece if preferred and be clamped, bolted or otherwise suitably connected to the wash down pipe on the one side and to the vessel A on the other. A hole or .passage 6 is formed in the side of the vessel A and extends through the V bracket or brackets a, a and through the pipe B sothat thelower chamber-or compartment a is thereby placed in communication with the interior of the pipe B.

In the passage 1) there is pivoted the lever or member C whose one'arm 0. projects into the, pipe B andwhose other arm 0 projects into the chamber a That end of the arm c which is in the pipe]? is preferably hollowed or made of spoon-shape on the top. The arm 0 which projects into the Clltlh lever C is weighted or heavier than the arm 0 so as to maintain the lever or-mems ber. C in its normally inoperative position see Fig. le-with the valve closed.

The valve D is shown in the form of a plug or coned valve and the plate a is shown constructed to provide a correspond ingly shaped seating (Z. (Z is a guide for the valve- The stem 612 of the valve is engaged by the arm 0 of the'lever when the latter is operated, and the valve D thereby raised andopened.seeFig. 1. v H E represents the small port, passage or conduit leading from a point at or near the bottom of the chamber a to the pipe B,

through which'the mixture of disinfectant and water flows from the chamber a into the pipe B,

The vessel A? is provided with a detachable or removable lid or cover a or other suitable means, for replenishing the disinfectant as required. a

In the'operation of the embodiment of our invention'illustrated in the drawings, the pull a is drawn down to discharge the water from the cistern A, down.the wash down? pipe B'to the pan C. The flushing stream in its passage? down the pipe B strikes the arm 0 of the lever C and moves the latter upon the pivot and causes it to assuine the position in which it is shown in Fig. 1. The inner arm 0 lifts and opens the valve D whereupon a quantity of the disinfectant falls. from the upper chamber a into the mixing chamber a Simultaneously the'spoon-shaped end of the lever C diverts a quantity of the water from the pipe D throu h the hole or passage 6 into the mixing 0 amber. where it mixes with the disinfectant. The mixture of water and disinfectant now runs out of the mixing chamber a? through the small passage or tom thereof for the mixture to conduit E into the pipe B. The small pas- 13 and into the pan C, after the main'flushw ing stream has ceasiil. This, as previously explained, insures the disinfecting of the water which remains in the pan until the flushing arrangement is again operated. Y

iVhatwe claim as our invention and desire to protect by Letters Patent is p 1. Disinfectingmeans :for the flushing'arrangement of water closets, urinals, sinks and the like, comprising a container for the disinfectant, a mixing chamber, a valve de vice for permitting a quantity of disinfectant to pass from the container to the mixing chamber, means for operating said valve which means comprise a pivoted lever the one end of which projects into the wash down or flushing pipe and is depressed by the main flushing stream and the other end of which contacts with and operates the valve, the end of the lever which projects into the wash'down. or flushing pipe also serving to deflect a quantity of the water into the mixing chamber, an inlet near the top of the mixing chamber through which the quantity ofwater deflected by the lever is admitted into the mixing chamber and an outlet from the mixing chamber at the botpass out into the wash down pipe.
